When you damage a creature with an attack or a spell and the creature's size is larger than yours, you can cause the attack or spell to deal extra damage to the creature. The extra damage equals your level. Once you use this trait, you can't use it again until you finish a short or long rest.

Your Constitution score increases by 2.

Wild raccoons can love 2-3 years, but you are capable of living over 20 years 

You’re about 45 cm tall and are around 20 pounds. 

Your base walking speed is 25 feet. Your speed can be reduced by heavy since you are small. Why would you even wear heavy armor as a raccoon anyways?

Accustomed to life underground, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You gain advantage on Wisdom (Perception) checks that rely on hearing or smell.

If being pursued or chased, raccoons gain advantage on Dexterity (Hide) and Dexterity (Stealth) checks.

You gain proficiency with the artisan’s tools of your choice: smith’s tools, brewer’s supplies, or mason’s tools.

Raccoons are experts at getting-by, finding food in the unlikeliest of places, and generally putting up with whatever conditions they're in, uncomplainingly.

You can get through anything. You always do.

Raccoons gain proficiency in the Survival skill.

You can speak, read, and write Common, Animal and Raccoon. Raccoon language is full of sounds that may sound similar but are different to the Raccoon expert, so most people won’t understand it.
